Nick,
I really don't remember what they sent back in the large envelope. After you
asked, I searched for the QSL I received sometime ago to see if anything
else was with it-a certificate or something. Just have the QSL's so I can't
answer the question.
I was part of a team that did a space shuttle QSL'ing and we sent out the
QSL only. It was a pleasure to read all the cards and see everything that
was sent to the Astronauts. I was amazed at how many contacts the SS made
as they sent a list for us to verify them by and only about 1/3 of the QSO's
requested a QSL. It seems to me that if you talk to an astronaut, you would
want to display a QSL in the shack for such an accomplishment.
All the cards were forwarded to NASA in Houston to the Astronauts that
actually performed the QSO's in Space. They wrote back and sent a great
poster to the team as a reward for volunteering to do the QSL's.
That's why I explained that the whole process takes time. Many people
involved and my hat is off to those volunteers that make us happy.
73,
Dee

Hi Dee,
I was fortunate to get a QSO with the ISS the other evening. I saw your post
about QSLs on the Amsat BB.
Just how large an envelope is needed? IRCs cost at least $2.10, so would $4
in postage be needed?
What do they send you along with a QSL card?
Thanks,

Nick,
I read the post earlier about the two IRC's. I think that went back to the
25th Anniversary Award we got back in Nov. 2008 - Jan. 2009. The
QSL cards my wife and I got in the past just took an regular SASE.
I hope this helps.

ISS Amateur Radio Status: July 13, 2010
SpaceCam planed for July 15-16
By Miles Mann WF1F,
MAREX-MG News www.marexmg.org
Manned Amateur Radio Experiment
Hi everyone:
Notes from the Ariss blog
http://ariss-sstv.blogspot.com/
MAI-75 activation planned for July 15-16 (updated)
An activity to support SSTV activation (MAI-75) has been schedule on July 15
and 16. Times fall between 12:00-15:00 UTC on the 15th and 10:00-12:00 UTC
on the 16th .
The system will be operating space cam in slide show mode and is expected to
use the Martin 1 format. The times are just over 1 orbit each day (two
passes over Moscow) so opportunities will be very limited.
***
That?s good news, it has been a while since we have had the Marex SpaceCam1
project on the air.
Note to ARISS and Sergej Samburov:
Slide Show Mode recommended Settings:
Kenwood TM-D700 Transmitter power set to Low/5 watts.
Image Delay setting 3 or 4 minutes.
Image Mode Recommendation, Robot-36
Keep the radio in a well-ventilated area.
The reason Marex recommends Robot-36 over the Martin-1 or Scotty imaging
modes is because of the transmission time required to complete an image.
The lower quality image Robot-36 only requires approximately 40 seconds of
transmission time to complete (Image time plus CW Id, etc).
A Martin-1 image, which is higher quality, requires 114 seconds.
Since all electronics run hotter in space, we need to make sure we do not
overheat the TM-D700 again, as happened before in August 2006.
Terrestrial testing has shown that SpaceCam running slide show mode at 5
watts, Robot-36, and a 3-4 minute image delay will give us the most images,
with an acceptable amount of heat loading on the Kenwood TM-D700.
If Martin-1 is required, then the delay between images will need to be
increased to 8-10 minutes between images, to allow the TM-D700 time to cool
down.
Optional Turbo Fan project for cooling the TM-D700
http://www.marexmg.org/fileshtml/turbofanproject.html
Tips for Working Slow Scan TV:
Will I be able to receive images from SpaceCam1?
Yes! SpaceCam1 will transmit and receive images on amateur radio
frequencies, using standard SSTV formats. Although SpaceCam1 is capable of
operating in several modes, the recommended format while in Slide Show mode
is Robot 36. This format offers the best standard compromise between image
quality and transmission time and heat stress.
In addition to two-way "interactive" operation, SpaceCam1 provides the
following fully automatic functions:
? Transmission from a live camera or disk at specified intervals
? ?Slide Show" operation from a set of images stored on the system
? SSTV Repeater
What equipment will I need to receive the images?
Radio receiver with an outdoor antenna. The radio receive will need to be
able to receive FM signals on 145.800 MHz radio band.
A PC with SSTV software or a dedicated SSTV scan converter.
For information on how to receive SSTV images from the International Space
station, check out the MAREX link:
http://www.marexmg.org/fileshtml/howtouseiss.html
Over the next few weeks we maybe receiving images from the International
Space station via Slow Scan TV (SSTV). The MAREX team will be collecting
these images from the amateur Radio and SWL community and we will post the
best.
We would like to collect all images received. However in order to properly
catalog the images we request you use the following image naming format.
After you receive you images; please rename the images using the following
format, All Lower case letters
Year 06, Month 07, Day 31, (UTC time), Call sign,
Short text description, .JPG
Example:
New format:
0607311905wf1f.jpg
I removed the first two numbers of the year and the ?Z? for UTC time.
All dates are assumed to be in UTC dates. The images coming down from ISS
will also have a time stamp embedded into the image. You can also use these
numbers to generate you file names. If you are a Short Wave listener and do
not have a call sign, just place your Initials after the time
(0607311905abc.jpg)
If we break this down
Year =06
Month = 07
Day = 31
Time = 1905 UTC
Call sign = wf1f
Description (optional) = Windows shot
Image format = jpg
Image Quality
Please do not put any text over lays on the images, Example, do not put web
page or advertisements in the image. Your own call sign and date are
acceptable.
Send all images directly to MAREX at
Marexmg@xxxxxxx.xxx
We would also like to know the following information in your email.
Name or Call sign
Country / State
Receiver
Software decoding tool
Elevation or range of ISS when you decoded the image.
Slide Show Mode:
The MAREX SpaceCam1 software contains a feature called ?Slide Show? mode. It
allows the crew to preload a directory full of images that will be
automatically transmitted to Earth. The crew will not need to keep pushing a
button to send images. In theory the system can run for weeks at a time
without crew involvement. The SpaceCam project will be able to transmit over
200 SSTV images per day (Robot 36 format).
Ariss has not announced any plans for a SSTV Uplink frequency.
SSTV Decoding Software
http://www.barberdsp.com/
There are many choices in SSTV software, some Free, others with more
features cost a few bucks.
http://www.marexmg.org/fileshtml/sstvlinkpage.html
So have fun, find your best setup and start practicing (on Earth) how to
decode SSTV on 2-meters.

All, I just finish making (with the help of my freind Jimmy, KZ7QCW) a Dual
beam yagi accoring to plans from Kent britain (WA5VJB). I Listened in on the
AO-51 pass at 004UT. I'm using my Kenwood TH-7D in duplex mode.
Heard a good signal and a few pile ups. I was able to tune for the doppler
pretty easy and kept a good signal. I tried to break twice, but couldn;t get
through, not sure it was me or the antenna (my guess would be me).
Even though i didn;t make a contact, I had fun listening and learned a bit
about how the communication process goes, so hopefully my next attempt will
be more sucessful.
I will be on AO-51 again for the pass at 0001UT 15 Jul. I'd appreciate
anyone listening for me (K7TEJ) from DM33.
Any advice & elmering is appreciated and welcomed.
73's and thanks in advance.

Welcome to satellites!
I remember making my first contact during a quiet pass. There was only one
station calling, so I had a good chance of my signal getting through. Had I
tried during a pileup, I might not have been heard.
My radio's an FT-817ND and, at first, I used the stock rubber duck antenna.
I soon found that it had limitations, so I got myself an Arrow dual-band
yagi. That made a lot of difference.
I've found that the greatest skills one needs for operating over satellites
is patience and a bit of luck, and I've done more listening than talking. I
also tried different birds and different passes and made some interesting
contacts that way.
Listen for me on the FM satellites, especially AO-51 and AO-27.

Hello Masahiro,
Thank you for your message! You have made a great observation, and I
think you are exactly right about the cause of the observed "glitches"
in the telemetry. Usually at this point in its orbit we would observe
AO-51 charging its batteries at a steady rate from fully illuminated
panels.
>From what I've read from page 43 here:
http://eclipse.gsfc.nasa.gov/SEpubs/2010/TP214171a.pdf the eclipse
was from 18:15 to 20:52 UTC. Look also at the areas experiencing
eclipse.
Please be aware that the "clock" on AO-51 runs fast. It is now about
3 minutes fast, so look at telemetry timestamped from about 18:18
until 20:55 UTC.
Since the duration of the solar eclipse was 2 hrs 39 min (or 159 mins)
and AO-51 orbits every 100 minutes or so, it could have been affected
two times.
I've plotted some of the telemetry collected from that period
(telemetry from 1800-2130utc) and posted it here:
http://www.amsat.org/amsat/ftp/telemetry/ao51/2010WOD/July2010/Wd071100_1800to
2130utc_solar_eclipse.xls
And here's a screenshot of AO-51 at the time:

Hi Shamai,
1) Do the front buttons on the LVB Tracker control the rotor?
2) Check the wiring to the LCD display (one bad connection can easily cause
this)
3) If it is not an LCD wiring problem, I would suggest programming another
PIC chip.

Today's ISS crew schedule shows VHF comm checks from the Russian segment
while over North America. Ground stations are at White Sands and Wallops.
The pass is from 20:00 UTC (west coast) to 20:15 UTC (east coast).
VHF-1 is 143.625 MHz FM, there may also be something on VHF-2 at 130.167 MHz.

Hi Nick,
It will be one of the constellation 36795 to 36801 - ?they all seem to be
fairly close together still.
I listened for both Tisat and Studsat last evening but didn't hear anything
so I am wondering if anyone has had recent success?

Hi Nick,
It will be one of the constellation 36795 to 36801 - they all seem to be
fairly close together still.
I listened for both Tisat and Studsat last evening but didn't hear anything
so I am wondering if anyone has had recent success?

Note:
When the VHF-1 transmitter is Running, the Amateur Radio receivers in the
2-meter band will go deaf (Receiving on 145, 490, 145.200, 145.990).
This is because the Transmitting antenna for VHF-1 is less than 50 feet away
from the Amateur Radio antennas.
The VHF-1 transmitter is usually left running for a few hours at a time for
ground stations to test against. If you wish to test this theory, just try
to ping the Amateur radio packet station ISS during a VHF-1 transmitter test.
When VHF-1 is transmitting, you will not see any packet activity, other than
internally generated Beacons on 145.800 (down 145.800, uplink 145.990).
When VHF-1 shuts down, normal packet access will resume.
Marex discovered this problem with the Mir Amateur Radio station. We then
custom designed a filter by DCI, to resolve the issues. No such filter
exists on ISS.

A couple of corrections to Miles' post.
Packet is on 145.825 simplex.
VHF-1 does de-sense the D700 radio but not completely (I have see a station
break through) but it takes a big gun to do so.
The VHF-1 transmitter is only planned to be keyed when in range of the US
ground stations as indicated by the crew timeline (10-20 minutes depending
on the orbit and number of ground stations in the footprint).
